An improved version of Li et al. ’s method of reversible data hiding of encrypted images is proposed. The original work partitions the encrypted image into two sets, and only one set is used for data embedding. After carrying out a feasibility analysis, the full embedding strategy is employed. Accordingly, the data embedding capacity is dilated. In addition, the corresponding new fluctuation measurement is designed for the full embedding strategy. The experimental results reveal that the full embedding strategy is effective and also indicate that using the new fluctuation measurement the performance is further augmented. The proposed method outperforms other works in terms of performance.
